Tea rose named Devilk

ABSTRACT

A new and distinct tea rose variety particularly distinguished by its continuous and profuse production of flowers of a relatively large size and of an Orange color carried singly on long, strong upright stems of a plant having a vigorous upright growth habit and an abundant production of foliage of relatively large size.

BACKGROUND OF THE NEW PLANT

This new tea rose originated as a seedling hybrid produced by me at mynursery at Pleasanton, Calif. by my crossing the variety `Sonia` (U.S.Plant Pat. No. 3,095) with pollen from the variety `Prominent` (U.S.Plant Pat. No. 3,380) and the present seedling of that hybridization wasselected by me for propagation because of the very Light Red colorationof its bloom and the sturdy long stemmed upright growth habit.Propagation of this selected seedling was done by me at Pleasanton,Calif. by budding with such success that under my direction, propagationof this new plant was continued through several successive generationswhich proved conclusively that the novel characteristics of the selectedseedling would hold true from generation to generation and appeared tobe firmly fixed and its homogeneity could be assured. This new plant isnow being propagated by budding at my nursery at Wasco, Calif.

DESCRIPTION OF THE DRAWING

This new tea rose plant is illustrated by the accompanying full colorphotographic drawing which shows flowers of the new variety in severalstages of maturity and with a color rendition that is as nearly true asthat herein specified as is reasonably possible to obtain byconventional photographic procedures.
